چكيده فارسي :
In this paper, the thermodynamic properties of a quaternary system including CaCl2 and Ca(NO3)2 as mixed electrolytes into the aqueous L-alanine mixture, using the potentiometric method, are reported. The potentiometric measurements were performed on the galvanic cells over total ionic strengths from 0.0100 to 4.0000 mol•kg-1 at T = (298.2, 303.2 and 308.2) K and P = 0.1 MPa. Data modeling was performed by Pitzer ion interaction model.
